“We have found a few bugs that are affecting battery life and we will release a software update to address those in a few weeks," Apple said in a statement to AllThingsD.

Some users of the device blame the low battery life on the many applications being run on the iPhone 4S.

Several of those applications include iCloud, Siri, Location Services, Bluetooth, Calendar and Reminder Sync, and automated diagnostic transmissions to Apple, among others.

The iDownloadBlog technology website believes that the iPhone 4S's battery issues are a bug in iOS 5's location service.

Thomas Clabrun, a writer for Information Week, gave his opinion on what may be the cause for this issue: "In general, anything that utilizes network connectivity is going to drain more power than an app that just runs locally. In my case, my battery performance is poor and I have not enabled iCloud, so iCloud isn't a suspect for me."

Apple has contacted iPhone 4S owners and asked them to install performance-profiling software for the time being, reported The Guardian.
